Pretty Flowers for my pretty hair

In a lot of the pictures of women with natural hair online, you will see them with gorgeous flowers in their hair.

I am crafty (somewhat, I do scrapbook pages and I am a beginner sewer) so I may try this when I am feeling motivated. But for right now I would just like to purchase a couple of flowers. Do you have any flower accessories? Where did you get them from?
